FOR GAS-PRODUCERS.

T 0 all whom it may concern:

Be it known that we, VICTOR E. Enwanns 111d JEROME R. GEORGE, citizens of the United States, residing at \Vorcester, in the county of lVorcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in the Feeding Mechanism of Gas-Producers, of which the following is a specification, accompanied by drawings, forming a part of the same, in which Figure 1 represents a central, vertical, sectional view of the upper part of the gas producer, having a feeding mechanism embodying our invention. Fig. 2 is a. side elevation of the top plate and hollow coal supporting shell suspended therefrom, and Fig. 8 is a top view of the coal supporting shell.

Similar reference letters and figures refer to similar parts in the diiferent views.

The object of our present invention is to provide a feeding mechanism for supplying coal to the heating chamber of a gas producer, whereby the coal is uniformly and evenly distributed within the heating chamher, and for providing means for protecting the feeding mechanism from the injurious effects of the excessive heat in the gas producing chamber, and it consists in the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

Referring to the accompanying drawings, 1 denotes the side walls of the gas producer, and 2 the inclosed gas producing chamber.

Supported upon the side walls 1 is a top plate or cover 3, having a central opening 4; surrounded by an upturned flange 5. Concentric with the flange 5 is a similar upturned. fian e (3, the space inclosed between the flanges o and forming a water space 7. Mounted upon the top plate 3, is a hoppershaped coal reservoir 8 having its lower end circular as at 9, and open for the delivery of coal. to the chamber 2. The circular open end 9 is inserted within theconcentric flange of the top plate and without the circular end 9-, is a depending flange 10, which enters the water space 7, thereby watersealing the lowerend of the coal reservoir. The'top plate 3 is provided with hollow bosses, preferably three in nhmber, arranged concern trically about the flange 5, said bosses, one of which is shown at 11, projecti ng upwardly through the water-sealed space 7 '1 he hubs 11 receive the screw threaded pipes 12 which are rigidly held in the hubs 11 by nuts 13, 1.4, which permit a vertical adjustment of the pipes 12. Rigidly attached to the lower ends of the pipes 12, and suspended therefrom is a cast iron shell 15, circular in plan view and having the equidistant lateral projecting lugs 16, provided with screw threaded holes to receive the screw threaded lower ends of the suspension pipes 12. The upper surface 17 of the shell 15 is a horizontal plane surface, supported concentrically with the circular lower end 9 of the coal reservoir S'and also concentrically with the gas producing chamber 2.

The diameter of the circular plane surface 17 is greater than the delivery opening in the lower end of the coal hopper 8 and the surface 17 is suspended atsucha distance below the lower end of the coal reservoir 8 that the mass of coal falling from the delivery opening of the reservoir 8 will be supported upon the plane surface .17 of the shell 15. J ournaled in the step-bearing 18 of the shell 15 and in the bearing 19 at the top of the coal reservoir is a rotating shaft 20, carrying at itsnpper end a worm gear 21 which is engaged to a worm 22 on a rotating shaft 23. Attached to the lower end of the shaft is a blade 2-1 with its lower edge in contact with the plane surface 17 of the shell 15 causing the coal resting upon the shell 15 to be scraped off thecircular edge 25 of the shell 15, and to fall by gravity in an annular ridge 26 within the gas producer chamber 2. The lower surface of the shell 15 is preferably concave as shown at 27 and is lined with some refractory material 28 such as asbestos or fire clay. One of the suspension pipes 12 communicates with a water supply pipe 29 through which a current of water is supplied to the interior of the shell 15, and one at the remaining pipes 12 is shorter than the feed pipe and serves as an over flow for the water supply to the shell 15, said over flow water falling into the water-scaled space 7 in which it is maintained at a constant level by an over flow pipe 30.

The operation of our improved feeding device is as follows: Goal is supplied in the reservoir 8 in the usual and well known manner in feeding devices of this class. The mass of coal which falls through the opening in the lower circular end 9 of the reservoir, is supported in a state of rest upon the V plane upper surface 17 of the shell spreading in each direction from the delivery opening of the hopper 8 as indicated by the broken lines 31. Rotary motion is then 1mparted to the shaft and scraping blade 24' by which the coal is scraped from the plane upper surface 17 of the shell 15 and caused to fall over the concentric circular edge into the gas producing chamber 2. During the operation of the producer a current of water is fed through one of the suspension pipes 12 to the shell 15 and into the water sealed space 7 of the top plate 3.

What we claim as our invention and desire to secure by Letters Patent is 1. A gas producer, having a heating c'ham ber provided with anopening in its top for the admission of coal, a nonrotatable coal receiving surface adjustablysuspended beneath said opening, a coal agitator above said coal receiving surface for moving the coal ofl said surface, and means extending upward from said surface for operating said coal agitator.

2. A gas-producer, having a heating chamber provided with an opening in its top for the admission of coal, a nonrotatable coal receiving surface adjustably suspended beneath said opening, a rotatable coal agitator above said coal receiving surface, and a shaft stepped in said coal receiving surface and extending upward therefrom for rotating said agitator. I

3. In a gas producer, the combination with a gas producing chamber having a cover provided with an opening for the admission of coal, of a nonrotatable coal receiving surface placed beneath said opening, means for adjustably suspending said coal receiving surface from said cover, and a movable member between said coal receiving surface and said cover for-removing the coal from said coal receiving surface.
